Week RecenT AdvAnces In Aquaculture Aquaculture consists in farming aquatic organisms. Around 500 BCE, the Romans farmed oysters and fish in Mediterranean lagoons, whereas freshwater aquaculture developed empirically some 1000 years earlier in China. Farming carp in ponds led to the complete domestication of this species in the Middle Ages, which is also when mussel farming began, following a technique that remained largely unchanged until the 20th century. https://www.alimentarium.org/en/knowledge/history-aquaculture Farming in ponds through the ages The earliest evidence of fish farming dates back to before 1000 BCE in China. The Zhou dynasty (1112-221 BCE), then the politician Fan Li, around 500 BCE, were the first to describe carp, a symbol of good luck and fortune, as being farmed for food. During the Tang dynasty, around 618, the Emperor Li, whose name means ‘carp’, forbade farming the fish that bore his name. Farmers then turned their attention to similar fish in the Cyprinidae family and developed the first form of polyculture. Liquid manure from livestock farming was also used to stimulate algae growth in ponds and make it more nutritious. -

Gulf Council Aquaculture Faqs
Gulf of Mexico Fishery Management Council Aquaculture Fishery Management Plan Frequently Asked Questions What is offshore aquaculture? Offshore aquaculture is the rearing of aquatic organisms in controlled environments (e.g., cages or net pens) in federally managed areas of the ocean. Federally managed areas of the Gulf of Mexico begin where state jurisdiction ends and extend 200 miles offshore, to the outer limit of the U.S. Exclusive Economic Zone (EEZ). Why conduct aquaculture offshore? Offshore aquaculture is desirable for several reasons. First, there are fewer competing uses (e.g., fishing and recreation) farther from shore. Second, the deeper water makes it a desirable location with more stable water quality characteristics for rearing fish and shellfish. The stronger waterflows offshore also mitigate environmental effects such as nutrient and organic loading. Are there currently any offshore aquaculture operations in federal waters of the United States? Currently there are no commercial finfish offshore aquaculture operations in U.S. federal waters. There are currently 25 permit holders for live rock aquaculture in the EEZ. There are also several aquaculture operations conducting research and commercial production in state waters, off the coasts of California, New Hampshire, Hawaii, Washington, Maine, and Florida. Why did the Gulf of Mexico Fishery Management Council develop a Fishery Management Plan (FMP) for regulating offshore marine aquaculture in the Gulf of Mexico? The current Federal permitting process for offshore aquaculture is of limited duration and is not intended for the large-scale production of fish, making commercial aquaculture in federal waters impracticable at this time. Offshore aquaculture could help meet consumers’ growing demand for seafood with high quality local supply, create jobs in coastal communities, help maintain working waterfronts, and reduce the nation’s dependence on seafood imports. -
Chilean Salmon Farming on the Horizon Of
11 Chilean Salmon Farming on the Horizon of Sustainability: Review of the Development of a Highly Intensive Production, the ISA Crisis and Implemented Actions to Reconstruct a More Sustainable Aquaculture Industry Pablo Ibieta1, Valentina Tapia1, Claudia Venegas1, Mary Hausdorf1 and Harald Takle1,2 1AVS Chile SA, Puerto Varas 2Nofima, Ås 1Chile 2Norway 1. Introduction Historically the Chilean economy has been based in exports accounting for 35% of the gross domestic product and mining is the main export income in the country. However, since 1980s as a part of a promotion the Chilean economy has diversified in part away from its dangerous over-reliance on copper exports. The growth of earnings in the fruit, wine, wood and forestry, fisheries and aquaculture sectors in particular, has been rapid since the early 1980s as Chile has exploited its comparative advantage in environmental endowment and low labour costs on the global market (Barton, 1997; Barton & Murray, 2009). The salmonid cultivation is restricted to regions with particular water temperature ranges in both fresh and seawater environments, sheltered waters and critically excellent water quality. Thus, salmonid aquaculture has become an important activity and the main development gear in the southern regions of Chile. The Chilean salmon industry has shown a fast development over the last 20 years and, therefore; today, Chile is the largest producer of farmed rainbow trout and Coho salmon, and the second worldwide of Atlantic salmon. This situation is the result from the application of innovation and development of value added products, which produced an average annual growth rate of 22% from 1990 to 2007 and an increase of exports from USD 159 million in 1991 to USD 2,242 million in 2007 (SalmonChile, 2007a). -

Received: 11 October 2019; Accepted: 15 December 2019; Published: 19 December 2019 Abstract: The multiple problems of modern agriculture urge people to probe into sustainability of the traditional agriculture. As important representatives of Chinese traditional agriculture, the agricultural heritage systems on aquatic-ecological conservation (AHSAEC) are confronting threats and urgently needs to be protected. In this study, the functions and value of the AHSAECs are analyzed by multi-disciplinary methods including system analysis methods based on the review of old books and modern scientific research literature, and the nature of their sustainability are discussed, and the countermeasures against their current unsustainability are proposed. -
FAO Fisheries & Aquaculture
Food and Agriculture Organization of the United Nations Fisheries and for a world without hunger Aquaculture Department Fishing Techniques Shrimp Otter Trawling Main Components Aquatic species Target Species Shrimps Gear types: Single boat bottom otter trawls Single boat bottom otter trawls A single boat bottom otter trawl is a cone-shaped net consisting of a body, normally made from two, four and sometimes more panels, closed by one or two codends and with lateral wings extending forward from the opening. A bottom trawl is kept open horizontally by two otter boards. A boat can be rigged to tow a single or two parallel trawls from the stern or from two outriggers. Vessel types: Otter trawlers These are trawlers on which the fish is preserved by freezing. Characteristics Shrimp otter trawling Species Environment Shrimps constitute one of the most valuable groups of marine species resources. Approximately 2 million tonnes are captured annually in world's fisheries. Targets in shrimp otter trawling encompasses a wide range of species in both tropical and temperate waters. Fishing Gear Trawls used in otter shrimp trawling encompass a range of designs and sizes. Shrimp trawls are typical made in relatively small meshes, with 20-60 mm in the codend. The mesh size in the belly part of the trawls seldom exceed 80 mm. Some larger shrimp trawls may have larger meshes in the wings, up till 100-200 mm. Vertical opening of shrimp trawls may range from less than 1 till 15-20 meters. Characteristic for otter shrimp trawling is that one or two trawls are towed from the stern of a vessel. -
Fisheries and Aquaculture in Japan January 2021
Fisheries and Aquaculture in Japan January 2021 Globally, fisheries and aquaculture production is an important source of accessible nutritious food, and abasisof livelihoods. It is also a key driver of coastal and rural economic well-being. However, overfishing, illegal fishing and the combined effects of ocean-based activities and climate change on resources and ecosystems put the sector atrisk and undermine the resilience of those relying on it in many places. Improving fisheries and aquaculture management is crucial to ensure future generations continue to benefit from Ocean resources and ecosystem services. The country notes of the OECD Review of Fisheries 2020 present each country’s situation in brief and identify best policy practices and reform pathways. These notes can also inform dialogue on progress towards internationally- adopted goals and targets with respect to sustainable fisheries and aquaculture management and support policies. Overview of the sector Fisheries and aquaculture production In 2018, Japan produced 4.2 million tonnes of fish (including molluscs and crustaceans), with a value of USD 13775.7 million. 38% of this value came from aquaculture and 62% from fisheries (that is, the capture of wild resources). Between 2008 and 2018, the quantity produced decreased by 25%, while its value decreased by 10%.

Utilization of Unique Tailwater Habitats Below High-Head Dams Has Become
Brown Trout Population Response to Trophy Regulations and Reservoir Discharge in a Large, Southeastern U.S. Tailwater by: David P. Dreves, Jeff R. Ross, and Jarrad T. Kosa Bulletin No. 111 March 2014 BROWN TROUT POPULATION RESPONSE TO TROPHY REGULATIONS AND RESERVOIR DISCHARGE IN A LARGE, SOUTHEASTERN U.S. TAILWATER By David P. Dreves, Jeff R. Ross, Jarrad T. Kosa Kentucky Department of Fish & Wildlife Resources March 2014 Partially funded by Sport Fish Restoration Funds Sport Fish Restoration Project F-40 “Statewide Fisheries Research” ABSTRACT Reservoir tailwaters can be an important resource for developing quality trout fisheries, especially when managed with special regulations. The objective of this study was to evaluate the effectiveness of a 508 mm minimum length limit and a one-fish-per-day creel limit on improving the size structure of the brown trout Salmo trutta population in the Cumberland River below Lake Cumberland, Kentucky. The purpose of the new regulations, which did not include gear or bait restrictions, was to increase the numbers of quality (381-507 mm total length) and trophy-size (≥ 508 mm total length) brown trout in the 121 km tailwater. A significant increase in brown trout electrofishing catch per unit effort was observed across years for small (< 381 mm), quality, trophy-size trout, and all sizes combined. As brown trout electrofishing and angler catch rates increased over time, no corresponding decrease in growth or condition was observed. Reservoir discharge was positively correlated with warmer water temperatures and lower dissolved oxygen in the tailwater. Growth and condition of brown trout in the tailwater were inversely correlated with an index of discharge from the reservoir. -

Aquaculture Research and Its Relation to Development in China
AQUACULTURE RESEARCH AND ITS RELATION TO DEVELOPMENT IN CHINA S.F. Li Shanghai Fisheries University, Shanghai, China E-mail: [email protected] ABSTRACT China has a long history in aquaculture that goes back 2500 years. However, key advances followed the artificial breeding of carp in the 1950s. This chapter focuses on the development from the 1980s to the present, discussing the major issues in the developments, current and future trends and challenges, and the roles of Shanghai Fisheries University and the WorldFish Center in addressing these concerns. STATUS Pond culture is the most important practice contributing to total aquaculture production from Dramatic development since 1980s freshwaters. Pond culture has an estimated share of 60 to 70 per cent of total freshwater aquaculture The history of fish farming in China goes back at least production, in which Taihu Lake area in the Yangtze 2500 years, and it has long held prominence in the River Delta and Zhong-Nan-Shuan area in the Pearl rich Chinese civilization. But it was only after the 1950s River Delta are the traditional centers of fish culture. that aquaculture has been rapidly developed. The Culture in open-waters (lakes, reservoirs, channels) and breakthrough in the artificial breeding of the silver carp, in paddies contributes most of the remaining output. bighead carp and grass carp achieved from 1958 to 1960 The most commonly farmed species are silver carp changed the traditional practice of collecting wild fry (Hypophthalmichthys molitrix), bighead carp (Aristichthys from the rivers.
